Can't pick which middle name we like better

My husband and I have looked forever for a middle name to go with Coral and we just have never been able to decide. Now with our first little one due to arrive any day now we have come up with two that we like but can't decide which one is better, please help us pick one. It's between Coral Ivory Gilbert or Coral Sephira Gilbert. If you think you have a better idea that is different and unique please let us know.
